Microsoft has confirmed that there are scenarios in which Service Pack 1 for Office 2010 deployments can fail, with users being unable to resolve the issue themselves.
The first upgrade for Office 2010 was released to manufacturing at the end of June 2011, when it also became available for download to customers around the world.
At the end of July 2011, the Redmond company started offering an update designed specifically to lower the rate of installation failures for Office 2010 updates.
